Does the youtube tutorial also applies to Redmi Note 3 2GB RAM/16GB ROM (non-pro) version?

I'm a new owner of RN3 Snapdragon (2GB RAM, 16GB ROM). My version is
Android: 6.0.1 MMB29M
Security patch level: 2016-11-01
MIUI version: MIUI Global 8.1 | Stable 8.1.1.0(MHOMIDI)

I hate advertisement so I rooted my old mi4i (Malaysia set) to install Adaway.

Read the first page about flashing etc but I still have questions
1) I don't have to unlock bootloader on mi4i to root, is it compulsory to unlock bootloader before I can root RN3?
2) The tutorial was released for MIUI 7.xxx, is it still applicable for my version?

Also has questions about mi4i, appreciate it of you guys can guide me as well.
After i rooted mi4i, my version remained MIUI 6.6.5.0(LXIMICF) Stable and never update OTA. I checked that the latest available update is MIUI V8.1.5.0 LXIMIDI | Stable | 970M
3) Is it the right way to update manually? Will my rooted miui bricked if I follow step 3a to 3d?

3a) download the zip file
Recovery: 969M

3b) save zip file into phone

3c) run Updater and 'choose update package'

3d) reboot device to update

Thanks

I've successfully unlock bootloader of RN3 officially after trying for 3 hours. There are 2 guides that help me the most.
In my scenario, based on my observation, the reasons that lead to 50% stuck is NOT due to xiaomi error per se, but it's due to PC not able to recognize "Android ADB Interface". Once the driver is installed, and the debugging bridge is able to link, unlock process just proceed smoothly.

I received the permission to unlock sms within 30 minutes!!! so fast.

The 2 most important guides (I don't follow exactly)

Guide 1) http://xiaomitips.com/guide/how-to-fix-cou...unlock-process/
- I skipped Step 3 & 8 & 9
- I disable "Verify apps over USB" in developer option
- still stuck at 50% after trying many times

Guide 2) http://en.miui.com/thread-136188-1-1.html
- after successfully install the adb driver, within 10 seconds the phone is unlocked

Just give Guide 2 a try, it may save many of your time.

additional observation:
I noticed that when I connect RN3 to PC, the default is "USB for charging" and I don't see Redmi Note 3 in Windows Explorer.
I have to choose "Transfer Files (MTP)" to access RN3 storage (Windows Explorer show Redmi Note 3).

After I install the above adb driver, the Redmi note 3 is shown in Windows Explorer before before i click MTP.

I guess this maybe the root of the problem. When in fastboot mode, there is no option to enable the linkage between PC & phone. After adb driver is installed, the linkage is automatic as soon as USB cable is plugged in.

Ya, i read someone complained about mistore selling Singapore set. As soon as I received phone from Lazada mistore, i called up xiaomi malaysia and ask them to verify. Luckily mine was Malaysia set. The staff admitted that they did receive complaints from buyers who received SIngapore set from lazada mistore.

Perhaps those who bought from Lazada mistore should check their IMEI here http://ecomm.sirim.my/SirimEnquiry/search_IMEI.aspx

i checked my IMEI again, which is confirmed Xiaomi Malaysia set
Cert Holder is XIAOMI MALAYSIA SDN BHD, not Era International

I suspect this Era International company source their phone both from Xiaomi Malaysia and other sources (Xiaomi Singapore?). Those from Xiaomi Malaysia cert holder is already registered. Those from XIaomi Singapore is registered under Era Int.

Can try to pm Xiaomi Singapore facebook to check IMEI and see what Xiaomi Singapore response??
